Two companies offering third-party support for Oracle’s open-source MySQL database, as well as the MySQL offshoot MariaDB, have announced plans to merge.

SkySQL, which was launched in 2010, said Tuesday it will merge with Monty Program, the company founded by MySQL creator Michael “Monty” Widenius. Terms of the deal, which is expected to close within several months, were not disclosed.

Widenius also created MariaDB, a fork of the MySQL codebase that is compatible with MySQL but offers additional features.

The combined company will provide support for all versions of MySQL as well as continued investment in MariaDB, according to a statement. SkySQL CEO Patrik Sallner will assume the same role, with Widenius serving as CTO.

Oracle’s January 2010 acquisition of MySQL’s former owner Sun Microsystems invited close scrutiny from antitrust authorities, particularly in Europe, after critics suggested Oracle might weaken MySQL in favor of protecting its flagship, proprietary database. Widenius played a public role in the debate, even calling at one point for Oracle to sell off MySQL.
